[Obesity and heart]

Area of Science:

• Cardiology
• Metabolic Health
• Obesity Research

Background:

• Cardiovascular complications are traditionally linked to obesity.
• Obesity's direct role in atherosclerosis is debated; indirect links via metabolic syndrome and diabetes are significant.
• The thrombogenicity of obesity contributes to atherosclerosis and embolism.

Purpose of the Study:

• To explore the complex relationship between obesity, adipose tissue, and cardiovascular health.
• To investigate the emerging concepts of myokines and the role of epicardial adipose tissue.
• To clarify the pathogenic versus protective roles of adipose tissue in cardiology.

Main Methods:

• Review of existing literature on obesity and cardiovascular disease.
• Analysis of the indirect mechanisms linking obesity to cardiovascular pathology.
• Examination of the "obesity paradox" in heart failure and other cardiovascular conditions.
• Inclusion of recent research on myokines and adipose tissue hormones.

Main Results:

• Obesity is indirectly linked to atherosclerosis through metabolic complications like diabetes and metabolic syndrome.
• The "obesity paradox" suggests better prognoses for obese patients in certain cardiovascular conditions.
• Epicardial adipose tissue has complex roles, potentially protective but also linked to coronary heart disease.
• Myokines from muscle tissue may offer protective cardiovascular effects.

Conclusions:

• Obesity presents more metabolic and cancer risks than direct cardiovascular risks.
• The precise role of adipose tissue in cardiovascular health (pathogenic or protective) requires further investigation.
• Adipose tissue, including that around the heart, can be beneficial in certain contexts.
